Coumarin 120 Chemical Properties,Uses,Production

Chemical Properties

Coumarin 120 is Light yellow beige powder

Uses

Coumarin 120 is widely used fluorophore, well-known for preparing fluorogenic substrates for cystine aminopeptidase and other hydrolases. Used as reference compound in enzyme assays.

Uses

suitable for determining polygalacturonase activity

Uses

λ max 354 nm in EthanolSuitable as laser dye and used as a fluorescent labeling reagent for trace determination of enzymes.

Purification Methods

Dissolve it in 5% HCl, filter and basify with 2M ammonia. The precipitate is dried in a vacuum and recrystallised from dilute EtOH. It yields a blue solution and is light sensitive. [Sigler Synthesis 614 1980, Kanaoka et al. Chem Pharm Bull Jpn 30 1485 1982, Beilstein 18/11 V 445.]
